Lost power steering in heavy rain

I was driving my wife's 07 WK 4.7 during a heavy rain storm today and a few times when I drove through a puddle, maybe about an inch or 2 deep, I lost power steering. It came back after about a minute each time.

It seems like it could be a loose belt that slips when it gets wet.

Has anyone else had this problem?
How did you fix it?

Either tension the belt or replace it. Also check and see if there should be a splash guard to help.keep the water out of the belt (not a WJ man, lol).

I've never heard of that happening with our trucks. I went through about 6-10'' of water during the peak of that storm today and the truck handled it beautifully. Maybe start with a Gator Belt and see if that helps?

My 3.7 used to do that with the OEM belt and OEM tensioner.
When I swapped out the belt and tensioner last year it went away.
I noticed the new replacement Dayco tensioner I bought has a larger pulley. It makes it kind of a pain to get the belt on but seems to add a bit more tension on the belt.
Haven't had an issue since. The belt slipping when you go through a puddle won't really hurt anything if you don't flog it, just ease off the gas a bit and it will grab.
